The Samrat Yantra, a giant sundial at Jantar Mantar, can measure time within two seconds, without any electronics or lenses.
Jantar Mantar in Jaipur, India, constructed in 1734 CE, features large-scale instruments including a gigantic sundial and quadrants designed for naked-eye astronomical measurements. The observatory allowed observation of celestial events, calculation of eclipses, and prediction of planetary positions. Unlike small-scale instruments, Jantar Mantar’s monumental structures amplified precision through sheer size. The observatory was also a center for research, teaching, and astronomical record-keeping. Its instruments were built according to mathematical principles, combining geometry and astronomy. The site demonstrates that pre-modern societies developed empirical observational tools capable of remarkable accuracy. Jantar Mantar continues to function as both a historical monument and a functional observatory for demonstrations. Its construction reflects a fusion of science, architecture, and statecraft.
